Numbers 27:19and have him stand before Eleazar the priest and before all the congregation, and commission him in their sight.

Numbers 27:21"Moreover, he shall stand before Eleazar the priest, who shall inquire for him by the judgment of the Urim before the LORD. At his command they shall go out and at his command they shall come in, both he and the sons of Israel with him, even all the congregation."

Treasury of Scripture

And you shall put some of your honor on him, that all the congregation of the children of Israel may be obedient.

And thou shalt put some of thine honour upon him,.... Meaning not the Spirit that was on Moses, and the gifts of the Spirit; for to do this was the work of the Lord, and not Moses, see Numbers 11:17, but of the honour of civil government; suggesting that he should give him a share in it, and use him not as a minister and servant, as he had been, but as his colleague and partner; and let him have some of the ensigns of power and authority, and some exercise of it; not only to inure him to government, but to make him respectable among the people:

that all the congregation of Israel may be obedient; to him as their ruler and governor, hearken to his words, and obey his commands.

20, 21. Thou shalt put some of thine honour upon him—In the whole history of Israel there arose no prophet or ruler in all respects like unto Moses till the Messiah appeared, whose glory eclipsed all. But Joshua was honored and qualified in an eminent degree, through the special service of the high priest, who asked counsel for him after the judgment of Urim before the Lord.

27:15-23 Envious spirits do not love their successors; but Moses was not one of these. We should concern ourselves, both in our prayers and in our endeavours, for the rising generation, that religion may be maintained and advanced, when we are in our graves. God appoints a successor, even Joshua; who had signalized himself by his courage in fighting Amalek, his humility in ministering to Moses, and his faith and sincerity in witnessing against the report of the evil spies. This man God appoints to succeed Moses; a man in whom is the Spirit, the Spirit of grace. He is a good man, fearing God and hating covetousness, and acting from principle. He has the spirit of government; he is fit to do the work and discharge the trusts of his place. He has a spirit of conduct and courage; he had also the Spirit of prophecy. That man is not fully qualified for any service in the church of Christ, who is destitute of the graces and gifts of the Holy Spirit, whatever human abilities he may possess. And in Joshua's succession we are reminded that the law was given by Moses, who by reason of our transgression could not bring us to heaven; but grace and truth came by Jesus Christ, for the salvation of every believer.
